Redmine

Hello,

I have a working Redmine 1.2.3 on Ubuntu 11.04 working.
I want to upgrade Redmine to 2.0.2 and I start the RedmineUpgrade HowTo.
I encounter a problem with: rake db:migrate RAILS_ENV=production

root# rake db:migrate RAILS_ENV=production --trace

  Tasks: TOP => db:migrate

My version of Rails is 3.2.5 and Ruby 1.9.3
Any idea??

Thank you.
